1/ Chronic pain and post-traumatic stress symptoms (PTSS) co-occur very commonly, yet how they interact in the brain is unclear. New from our lab: trauma symptoms reorganize working memory circuits in chronic pain, even when behavior looks normal. Veinot & Hashmi, PAIN, 2026 🧵

true story 😂

What happens when the brain slips into a microsleep? An example from a highly drowsy participant showing a brief loss of responsiveness (at time 0s). Details of the research: www.biorxiv.org/content/10.6...

Had me cackling like a fool 😭

Shrey spelling 32 words in 90 seconds to win the Spelling Bee is the new greatest athletic accomplishment of 2026. I don’t even know how he said the letters that fast. Got a “Holy Mackerel” out of @minakimes.bsky.social

AI trained with input from experts: scientists, clinicians and patients, very carefully and cautiously may solve problems instead of creating new ones. See our paper:

PAIN@painthejournal.bsky.social · 2mo ago

Hashmi et al. argue that AI and machine learning could transform chronic pain care by identifying objective biomarkers and patient subtypes, though rigorous validation and clinical integration remain essential. Learn more in #PAIN bit.ly/4cIZDpl

discussion will include "potential interventions (e.g., moving to one competition per year, restricting applications, capping resubmissions)." don't miss this

CIHR has launched a trial ballon that suggests shifting to one competition a year. This is the worst idea I have heard in a long time. The only benefit is making top-line success rates look better than they are. Keep it as is, do in-person reviews, and keep the pain in the open.

Diffusion MRI (dMRI) is a powerful tool to study white matter maturation. In our new preprint, we process and distribute a new resource of >24,000 ABCD dMRI scans using open source tools! We then evaluate how methods shape inferences about development. 🔗 www.biorxiv.org/content/10.6...

New paper in PNAS! When the mind wanders, it often drifts to the body. We call this "body-wandering". These thoughts are often negative, but are associated with reduced ADHD & depression symptoms, driven by a distinct interoceptive-allostatic brain signature. pnas.org/doi/10.1073/pnas.2520822123

More evidence that the homeostatic pathway lamina 1 theory has no feet.

Is there a single "interoceptive sense"? Our new study in @commspsychol.nature.com says: probably not. In 241 participants, cardiac and respiratory interoception were completely uncorrelated — only subjective confidence was shared across domains. www.nature.com/articles/s44... #psychscisky 🧪
